Hey guys, I need some really nice speakers for the front and rear, and a head unit for now.

What brands do you guys recommend in terms of component speakers for the front and coaxials for the back. They have to sound really good, but not cost me an arm and a leg.

The most I am willing to spend is $500 - $600 for both front and rear.

Also need a nice head unit that has alot of features, and a good display with nice sound quality as well.

Also what kind of amp would you suggest to go with the speakers. I don't want to spend more than $1200 for now so please help me out, in choosing some nice ones.
